E46 M3 - dealer or independant recommendations ?

[RSpiston]

Long shot warning.

Anyone have first hand recommendations of either a dealer or independant garage that knows the E46 M3 inside out ?

Caveat is......must be based in Northern France. Normandy or nearby.

There you go - told you it was a long shot !

Would have helped if you had put the location in the title!
